Pseudolymphoma of the liver: Sonographic findings and review of the literature

Abstract

We report a case of hepatic pseudolymphoma in a 67-year-old woman that was detected during an abdominal sonography screening. The lesion was further evaluated using CT, MRI, angiography, and contrast-enhanced sonography. The imaging features of this tumor are discussed herein. The diagnosis of pseudolymphoma was achieved via sonographically guided biopsy. The lesion regressed completely within 1 year.

Hepatic pseudolymphoma: a clinicopathological study of five cases and review of the literature

“…All cases reported in English are reviewed in Table 2. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] The total number of cases was 26, including 5 patients in the current study. Five patients (19%) had multiple (two or three) lesions.…”

Multinodular pseudolymphoma of the liver: computed tomography and magnetic resonance imaging findings

“…[1][2][3][4][5] Most of the lesions reported are single in number, although multiple lesions have been also reported. [1][2][3][4][5] Usually there are just two or three lesions, however, with a large number of lesions as in our case never having been reported to the best of our knowledge.…”

“…[1][2][3][4][5] Imaging fi ndings of PL, although only a few case reports are available, are thought to refl ect these pathological features but are considered nonspecifi c. On CT, a hypodense mass on unenhanced images that is slight enhanced on early-phase images after contrast injection and subsequent washout have been reported. [1][2][3][4][5] On angiography, neovascularity and tumor stain have been documented. 4 On MR imaging, low signal intensity on T1-weighted images and slightly high signal intensity on T2-weighted images have been reported.…”

“…Its association with autoimmune disease, malignancy, and hepatitis has been reported. [1][2][3][4][5] The imaging fi ndings of PL are nonspecifi c and resemble those for any other vascular tumors of the liver, which make its noninvasive diagnosis diffi cult. We herein present a case of multinodular PL in which a small vessel was observed to course within one of the lesions on multidetector row computed tomography (MDCT), and partial uptake of liver-specifi c contrast agent was observed in the lesion on magnetic resonance imaging (MRI), both of which might be characteristic of hepatic PL.…”
